The method involves determining whether freezing condition is fulfilled to indicate a differential pressure sensor (1) is frozen. A default value for a sensor signal is used if the freezing condition is fulfilled. Determination is made to find whether curing condition is fulfilled to indicate that the differential pressure sensor is not frozen. A value of the sensor signal is used if the curing condition is fulfilled, where frozen state of the sensor comprises frozen state of connection lines (2, 3) of the sensor. An independent claim is also included for a device for detecting frozen state of a differential pressure sensor in an exhaust gas tract of a motor vehicle.

Method of treating or identifying faults in an exterior temperature sensor of a vehicle based on temperature gradient

The method involves determining a temperature gradient from the temporal cycle of the measured temperatures. The gradient is compared with a predetermined threshold gradient and faults are determined based on the comparison. A first fault is identified if the gradient is positive and greater than the threshold. A second fault is identified if the gradient is negative and greater than the threshold. A differentiation is made between two different faults or groups of faults according to the sign of the gradient. Independent claims also cover apparatus for diagnosing a temperature sensor.

Method and device for diagnosing an external temperature sensor

Номер: US2007036197A1
Автор: HUTTENLOCHER MARTIN, SOUCEK LIBOR
Принадлежит:

A method and apparatus for fault recovery and/or fault detection of an external temperature sensor of a motor vehicle, in which a temperature gradient is determined from the profile of the measured temperatures over time, in which the determined temperature gradient is compared with a predefined or predefinable limiting gradient, and in which a fault is detected as a function of this comparison.
